Jose Bonifacio S. Rafanan M.D.Fellow, Philippine Academy of
Rahabilitation Medicine
Outline Definition: Concepts in therapeutic exercises Benefits of exercise Local and systemic effects of
exercise Types of exercises Components of exercises Parameters of exercises Forms of exercises Facts and fallacies about exercise
Therapeutic exercise
Exercise: Muscle being used in some type of
exertion causing motion of parts of the body
Therapeutic: Exercise as a part of a treatment
program under medical supervision and appropriately prescribed by a physician
Benefits of exercise
Lifetime health and fitness benefits Increase in high density lipoproteins Decrease in triglycerides Improved lung function Helps reduce blood pressure, anxiety and
depression Control weight Increase the body’s ability to dissolve blood
clots by increasing fibrinolytic activity Increase levels of endorphins Helps the bones to be stronger – inhibiting
osteoporosis Offers protection against diabetes and cancer
Concepts in Exercises: Overload Principle:
Greater stress must be applied than that to which an organism or tissue is accustomed in order to have adaptation take place
Strengthening program must tax muscle groups towards it maximal capacity and beyond its usual functional capacity
To increase strength, a load that exceeds the metabolic capacity of the muscle must be used during exercise, this will lead to hypertrophy and recruitment resulting in increase in strength
Concepts in exercise
Adaptation Cardiovascular system and
muscles adapt to the training stimulus over time
Significant changes noted in 10 – 12 weeks
The higher the initial level of fitness, the greater the intensity of exercise needed to elicit a significant change
Concepts in Exercise
Reversibility principle: Beneficial effects of exercise training are
transient and reversible After only two weeks of detraining,
improvement begin to be lost Frequency and duration of physical
activity needed to maintain a certain level of aerobic fitness is less than that required to improve it
Concepts in Exercise
Specificity of training: Exercise adaptations are directly related
to the nature of the exercise stimulus No strength training program will give a
100% carry over to a sporting or functional activity unless the specific sports or functional activity makes up the training program
Adaptive effects of training are highly specific to the training methods used
Effects of exercises
Acute or immediate effects Chronic, adaptive or training
effects
Local effects Systemic effects
Acute Effects
Start of exercise:increase heart rateincrease cardiac outputIncrease in blood pressureincrease in venous returnincrease in arterio- venous O2
difference
Systemic effects
In isotonic exercises decrease peripheral vascular
resistance increase in muscle blood flow
In isometric exercises Decrease in local blood flow to the
contracting muscles Increased blood pressure
Systemic effects As exercise continues at constant rate:
Steady State: heart rate Blood pressure
Cardiac output• At the end of exercise:
• Initial rapid drop in heart rate then slower return to normal
• Decrease in blood pressure sudden if exercise is stopped abruptly
Systemic effects
If exercise is greater than the body’s ability to maintain: Heart rate plateaus at maximal level Decreased stroke volume, arterial
blood pressure Constant O2 consumption
Fatigue sets in
Systemic effects respiratory effects:
Respiratory rate increases: 5 – 6 times in maximal exercise
Tidal volume increases: 5 – 7 times Hormonal effects:
Decrease insulin production Increase glycogen production Increased catecholamine, in intense exercises Increase in growth, adrenocorticotrophic,
TSH, adrenal and androgens
Systemic effects
Post exercise syncope Seen after vigorous exercise Pooling of blood in the exercised
extremity Hypotension Catecholamine release – risk of
developing dysrhythmia, cardiac ischemia
Systemic effects
Arm exercises vs. leg exercises: Higher systolic and diastolic blood
pressure Higher heart rate Higher oxygen uptake
Exercise should use workload 40 – 60 % lower than those used for LE in order to obtain systemic effects
Local effects
In the muscles being exerted: Increased oxygen extraction Increased oxygen consumption Increased carbon dioxide production vasodilatation
Local effects
During isometric contraction: Complete occlusion of blood flow 70% of maximal voluntary contraction
level Depletion of energy substrates
During isotonic exercise: Slow twitch fibers first to lose glycogen
then followed by the fast twitch fibers
Parameters of exercise
Mode of exercise: Aerobic vs. anaerobic exercise
Intensity of exercise Duration of exercise Frequency of exercise

EXERCISE PROPERPOST EXERCISE COLD DOWNPOST EXERCISE STRETCHING 1
04/19/23
PURPOSE OF WARM UP
to raise the general body temperature to raise the deep muscle temperature - contracts more forcefully and relaxes more
quickly to stretch collagenous tissue to reduce muscle viscosity, improving the mechanical efficiency to increase the speed of nerve impulses and augment the sensitivity of the nerve
receptors to improve the cardiovascular response to sudden exercise
2

TYPES OF WARM UP RELATED WARM UP
when the specific skills of an event are performed during the warm up
preferred if activity starts slowly and progresses into more intense activity
UNRELATED WARM UP when movements performed are different
from the actual skills of the activity or event preferred if immediate participation in the
actual activity is required 3
04/19/23
WARM UPS
15 - 20 minutes intensity and duration should be
individualized enough to increase body temperature
and perspire, not too intense to cause fatigue
usually coupled with few minutes of high intensity exercise to result in better performance 4
Warm up
the effects of warm up last up to 45 minutes the closer the warm up to the event, the
more beneficial it will be in terms of effective performance
should begin to taper off 10 - 15 minutes prior to the training or competition/ event
should end 5 minutes before the start of activity - to allow recovery from fatigue

STRETCHING
GOAL: to improve the range of motion at a given articulation by altering the extensibility of the musculotendinous units that produces the movements

TYPES OF STRETCHING
BALLISTIC STRETCHING STATIC STRETCHING PNF STRETCHING PASSIVE STRETCHING ACTIVE STRETCHING
6
04/19/23
BALLISTIC STRETCHING
requires repetitive contraction of the agonist muscle to produce quick stretches of the antagonist muscles
ADV: simulate sports specific skills - functional
7
Ballistic stretching
DISADV: predispose to muscle strain rapidly stretched muscle may increase
intrafusal muscle spindle activity causing protective muscle contraction
higher level of muscle soreness due to small tears in connective tissues and muscles
fails to provide tissues an adequate time to adopt to a stretch
should be done after a static stretch
STATIC STRETCHING passive or active stretching a given
antagonist muscle by placing it in a maximal position of stretch and hold it for an extended time
3 seconds to 60 seconds three to four times
Static stretching
ADVANTAGES: requires lesser energy expenditure lesser degree of exceeding normal range of
motion less muscle soreness allow adequate time to reset the sensitivity
of the stretch reflex can induce muscular relaxation via firing of
the GTO if the stretch is held long enough
PNF STRETCHING
AKA: muscle energy release technique
techniques: contract - relax contract - relax - contract
commonly used with athletes and individuals with limited range of motion
TYPES OF STRENGTHENING EXERCISE
ISOMETRIC EXERCISES ISOTONIC EXERCISES ISOKINETIC EXERCISES
Types of exercise
Isometric exercise: Static exercise with
muscle contraction but no movement of the load resulting in no change in the total length of the muscle
Type of exercise
Isotonic exercise: Dynamic exercise
with a constant load but uncontrolled speed of movement
Type of exercise
Isokinetic exercise: Exercise with movement
controlled so that it occurs throughout a range at a constant angular velocity as the muscle shortens or lengthens but the load may be variable
Exercise goals
To increase muscle strength To increase muscle endurance To increase speed To improve cardiovascular fitness To improve flexibility To improve control and
coordination
MUSCLE STRENGTH AND ENDURANCE
STRENGTH: ability of the muscle to generate force against some resistance
ENDURANCE: ability to perform repetitive muscle contraction against some resistance of an extended period of time
POWER: large amount of force generated quickly; includes elements of strength and speed
CLOSED KINETIC CHAIN EXERCISES
ADV: safer and produce stresses and forces that are potentially less of a threat to healing structures
e.g. mini squats - 0 - 40 degrees leg press stair climbing lateral step up push ups , chin ups hand stands weight shifting exercises using medicine
balls
CARDIOVASCULAR ENDURANCE
CONTINUOUS TRAINING imposes submaximal
energy requirement that is consistent throughout the training session
e.g. aerobic/ rhythmic walking, jogging, rowing, cycling, swimming
Cardiovascular endurance
INTERVAL TRAINING uses a series of exercise stations that
consists of various combinations of weight training, flexibility, calisthenics, brief aerobic exercises
CARDIOVASCULAR ENDURANCE
CIRCUIT TRAINING followed by relief stations
incorporates work intervals FARTLEKTRAINING
types of cross country running, means speed play, similar to interval training
PLYOMETRIC EXERCISES: exercises that encompasses a rapid stretching
of muscle eccentrically, followed by a rapid concentric contraction
the greater the stretch before concentric contraction, the greater the resistance the muscle can overcome
emphasize the speed of the eccentric phase of rate of stretch is more critical than the magnitude of the stretch
Plyometric exercises
ADV: control in dynamic movements DISADV: put more stress on the MS
system, must be technically correct and specific to one’s age, activity and physical and skills devt.

transfers Perineal care and
hygiene Ambulation Dressing
FALLACY:
SPOT REDUCTION CAN REDUCE THE AMOUNT OF FAT IN CERTAIN PARTS OF THE BODY
FACTS
EXERCISE, EVEN WHEN LOCALIZED, DRAWS FROM ALL OF THE FAT STORES OF THE BODY
DECREASE IN GIRTH IS A RESULT OF INCREASE IN MUSCLE TONE
HIGH INTENSITY AEROBIC EXERCISES USES 65% OF THE BODY ENERGY STORES WHILE LOW INTENSITY EXERCISES USES MORE FAT AS AN ENERGY SOURCE BUT IT DOES NOT NECESSARILY LEAD TO A GREATER EXPENDITURE OF CALORIES
FALLACY EXERCISE AND SPORTS
WILL DETER BONE GROWTH IN CHILDREN
FACTS
EXERCISE AFFECTS PRIMARILY BONE WIDTH, DENSITY AND STRENGTH BUT DOES NOT AFFECT THE BONE LENGTH
EXERCISE ALONG WITH ADEQUATE DIET IS ESSENTIAL FOR PROPER BONE GROWTH
SPORTS ONLY CONTRIBUTE TO ABOUT 23% OF EPIPHYSEAL INJURY IN CHILDREN
COMPETETITVE BASEBALL, TENNIS AND SWIMMING CARRY HIGHER RISKS FOR SHOULDER INJURY IN CHILDREN
FALLACY
WHEN A FAT BABY GROWS UP, BABY FAT WILL DISAPPEAR
FACTS
FAT BABIES MAKE FAT ADULTS FAT CELLS ARE FORMED DURING
THE FETAL DEVELOPMENT UP TO DEATH
FAT HYPERPLASIA OCCURS WHEN EXISTING FAT CELLS CONTINUE TO FILL WITH FAT TO A CERTAIN CRITICAL VOLUME
FALLACY
STRENGTH TRAINING IS CONTRAINDICATED IN CHILDREN
FACTS
PREPUBESCENT CHILDREN CAN IMPROVE STRENGTH WITH RESISTANCE TRAINING DUE TO SYNCHRONIZATION OF MOTOR UNITS FIRING. IT IS ONLY DURING PUBESCENT PERIOD THAT INCREASE IN STRENGTH IS DUE TO INCREASE IN MUSCLE MASS
RESISTANCE TRAINING IS ALLOWED IN CHILDREN WITH THE PROPER GUIDANCE OF A TRAINED WEIGHT TRAINOR
FALLACY
THERE IS AN INCREASE IN METABOLIC RATE AFTER EXERCISE ( EXCESSIVE POST EXERCISE OXYGEN CONSUMPTION) REGARDLESS OF THE TYPE OF EXERCISE.
FACTS
E.P.O.C. IS INCREASED DEPENDING ON THE INTENSITY OF EXERCISE
FALLACY
SOME HEALTH FADS ARE MORE EFFECTIVE THAN OTHERS
FACTS
THE MOST IMPORTANT FACTOR IN WEIGHT REDUCTION IS THE DEVELOPMENT OF A CALORIC DEFICIT WHILE MAINTAINING A COMPLETE BALANCED DIET THAT MEETS THE BODY VITAMINS AND MINERAL REQUIREMENT
FALLACY
DIET AND WEIGHT RESISTANCE TRAINING ARE THE BEST COMBINATION IN DECREASING BODY WEIGHT.
FACTS
DIET AND AEROBIC EXERCISE DECREASES BODY WEIGHT AND PERCENTAGE BODY FAT BUT MAINTAINS FREE FAT MASS
FALLACY
EXERCISE IS AN APPETITE STIMULANT
FACT
EXERCISE APPEARS TO BE A MILD APPETITE SUPPRESSANT FOR THE FIRST FEW HOURS FOLLOWING INTENSE EXERCISE TRAINING DUE TO AN INCREASE IN CATECHOLAMINE
